Maharashtra State Fly ash Policy 2016 Initiatives by Maharashtra State Fly Ash Council
POWER GENERATION SCENARIO
• India is world’s third-largest power consumer.
• India is 3rd largest Coal based power generator as 66% is derived from coal.
• India is the world’s second largest coal consumer. Huge quantities of Ash is generated as our coal contains over 40% Ash.
• By 2031 ash generation is expected to be 900 Million Tons
India has vast coal reserve of 211 billion tones
making coal the most extensively used fossil fuel for
generating power in the country. In order to achieve
self-sufficiency in energy sector the Government of India has announced ambitious targets for domestic
coal production of 1500 Million Ton coal per annum
by 2020-21 out of which 900 Million Tons (60%)
coal is expected to be used for thermal power
generation.
Coal to Power India for decades
With 35 % to 50% ash content in Indian Coal about 900 Million
Tons ash generation is expected annually by 2031. 20% ash is
collected in combustion chamber as Bottom Ash and 80% ash is
collected in Electrostatic Precipitators as Fly Ash. Bottom Ash
and unutilised Fly Ash is mixed with water and pumped to Ash
Pond through pipeline. Indian Fly Ash contains 26% Alumina,
59% Silica, 4% Magnetite, 3% Calcium & other minerals.
Fly Ash disposal – a Challenge
In Maharashtra about 25 Million Tonne Fly Ash
is expected to be generated annually as the
coal contains >40% ash
About 22,000 Acres of land will be required
for disposal of Ash as about one Acre of land
is required per MW of installed capacity

Challenges before Maharashtra – A Resource Opportunity
• Energy is critical, directly or indirectly, in the entire
process of evolution, growth and survival of all
living beings and it plays a vital role in the socio-
economic development and human welfare of a country.
• Energy has come to be known as a `strategic
commodity’ and any uncertainty about its supply
can threaten the functioning of the economy.
• Generation of fossil fuel based energy has initiated Climate change which is a major challenge for developing countries like India that face large scale climate variability and are exposed to enhanced risks from climate change.
• Rapid urbanization in the country will be one of the most dominant trends in the coming years.
• It is expected that about 40% of the population of India in 2030 would be urban as against 30% in 2008.
• However in Maharashtra 58% of population will be urban by 2030.
• The Fly Ash Utilization Policy addresses the above issue by 1. Promoting utilization of Ash in dry form.
2. Reduce cost of transportation of Ash by setting up Fly Ash based Industrial clusters within vicinity of all Power
Plants. By effectively implementing the State Fly Ash Policy over Rs 8,000 Crores can be saved which can reduce the cost of Power.
It will also save 20 Million Cubic meters of water annually.
Maharashtra State Fly Ash Policy 2016
In view of above it has become necessary for the State to formulate a Policy
“To promote use of 100% Fly Ash without compromising the need for Generation of adequate power for Maharashtra on a
sustainable basis at competitive rates in a socially responsible manner” • To fully meet the future needs of the State housing sector
for Fly Ash based building material. • To achieve 100% Fly Ash Utilisation.
Maharashtra State Fly Ash Policy 2016

Delhi High Court National Highways Authority Of ... vs Hindustan Construction Co Ltd on 7 December, 2018 • with regard to fixing of claim number of new / appropriate rate for varied works
of construction of the embankment at Ramsnehighat Bypass with borrow earth obtained from the contractor's borrow areas, in place of flyash embankment as provide for in the contract
• Engineer directed HCCL to use borrow earth instead of flyash which would result in a saving of additional cost of Rs. 6 crore by NHAI. It was for this reason that the majority concluded that this decision was for the commercial and economic benefit of NHAI. Indeed, the original scope of the work envisaged the embankment at the Ramsnehighat Bypass being constructed entirely of flyash
• we are not inclined to interfere with the said conclusion against this claim. • we do not see any merit in the appeal. The same is dismissed. No costs.

To,
The Chief Secretaries of all the State Governments/UTs. 1. Fly-ash is causing environmental pollution, creating health hazards and requires large
areas of precious land for disposal. Due to increasing concern for environmental protection and growing awareness of the ill effects of pollution, disposal of ash
generated at thermal power plants has become an urgent and challenging task.
2. As per MORTH 'Specifications for Road and Bridge Works' and IRe 'Manual of Specifications and Standards' (two, four and six laning of Highways etc.), use of fly-
ash shall conform to the MoEFCC guidelines. As per the Ministry's Specifications for Road and Bridge Works use of fly ash is allowed under Section 305 for "Embankment
Construction". The physical and chemical properties of fly-ash and the design
methodology to be adopted for embankment construction has been specified in IRC: SP: 58-2001 "Guidelines for use of fly-ash in Road Embankments".
3. In view of the above, it is hereby once again requested to use fly-ash in the road construction, in line with the guidelines of MoEFCC, MORT&H and IRe.

Subject: MoU for off-take of Fly Ash from Private Power Stations.
Please find enclosed herewith a copy of letter No. APP/DG/2018-19/1148 dated 04.12.2018 regarding
MoU with NHAI for off-take of Fly Ash from Private Power Stations received from Sh. Ashok Khurana,
Director General of Association of Power Producers (Copy enclosed).
2. As per the notification of MoEF, it is mandatory to use fly-ash in construction of roads or flyover
embankments within a radius of 300 km of thermal power plants. The NHAI has signed an MoU with some NTPC stations for off-take of fly-ash in this regard. However, several of APP members are reportedly facing
challenges in off-take of fly ash as no MoU has been entered into with the NHAI/PWD in line with NTPC.
3. Further, it is to mention that the Association of Power Producers has reported vide above mentioned
letter that all Power stations are willing to enter the pro-forma MoU with NHAI as per the terms and
conditions specified by the MoEF. Accordingly, it is requested that the NHAI and all other project executing agencies of MoRTH are mandated to use flyash generated from private thermal stations/ plants for construction
of embankments as per the provisions of MoEF guidelines and, accordingly, a MoU may be signed with the
Private Power Generating Stations as well and fly-ash used from these stations for the said purposes.
